[citation needed] It is a fairly common isolated anomaly which often goes unnoticed, but also occurs in combination with other abnormalities in certain genetic syndromes.
[citation needed] Clinodactyly can be passed through inheritance and presents as either an isolated anomaly or a component manifestation of a genetic syndrome.
[citation needed] But the phenotype, by itself, is not a sensitive or specific diagnostic test for these syndromes (it is present in up to 18% of the normal population[3]).
When identified prenatally, in conjunction with other features of Down syndrome, for example during obstetric ultrasonography, it may be an indication for intrauterine sampling for fetal chromosome analysis.
Severe clinodactyly may require soft tissue alterations to the digit such as release of skin, extensor tendon relocation, and collateral ligament advancement.
